(10)  Income Taxes

For the three months ended October 31, 2012 and 2011, we recorded $0.1 million and $0 in income tax expense, respectively. For the nine months ended October 31, 2012 and 2011, we recorded $0.4 million and $0 in income tax expense, respectively. The increase was primarily due to the increase in taxable income in our international jurisdictions.

There were no material changes to our unrecognized tax benefits in the nine months ended October 31, 2012, and we do not expect to have any significant changes to unrecognized tax benefits through the end of the fiscal year. Because of our history of tax losses, all years remain open to tax audit.
